Ios 为什么UITableView在模拟器上不同？

我是iOS开发新手，我想知道为什么当我启动模拟器查看我的表视图时，它会创建垂直滚动，但我在故事板上的表视图中看不到任何滚动

为什么会这样

我应该强制每个设备的宽度和高度吗（例如：iPhone4、iPhone5、iPhone6）？你知道是否有一个“自动”选项可以为每台iphone扩展我的应用程序，还是应该为iphone4、iPhone5和ipad创建一个新的应用程序

提前感谢。

必须包括iphone/ipad的所有默认屏幕，请按照所有步骤包括发布图像，并且您的发布图像大小为

UITableView是UIScrollView的子类，因此它继承了ScrollView的所有属性

是的，您必须在代码中为每个手机大小设置TableView的边框大小。要了解有关视图、视图大小和框架等的更多信息，请参阅联机提供的任何常见编程指南。（我个人推荐）

不，您不需要为每个平台构建单独的应用程序。您只需要为它们管理视图

我把它包括在哪里？我的问题是视图而不是图像。您必须包含default.png和default2x@.png在你的项目中…对于spash Screen，它不起作用…仍在创建一个滚动，并且我在界面设计器（故事板）上看不到任何滚动
